When the clinic has no water.

Water stress is written about as a crop problem and a drinking water problem. Almost nobody writes about what it does to a health facility. When water fails, infection control is the first casualty: hands cannot be washed between patients, instruments cannot be cleaned, surfaces cannot be cleaned. Procedures get deferred. Deliveries move somewhere else, or happen at home. Staff who have to fetch water for their own households come in late or not at all. The facility is still open. It is not, in any sense a patient would recognise, available.

That is the Available condition of climate-access failing in its plainest form, and the global data now makes it possible to put a scale on it.

How many health facilities have water?

Most, on paper. The WHO/UNICEF Joint Monitoring Programme's report of 18 August 2026, covering 2015 to 2025, estimates that 85 per cent of health care facilities had a basic water service in 2025, 72 per cent had basic hygiene services and 71 per cent basic health care waste management. Only 59 per cent met the basic standard for environmental cleaning, and 40 per cent the basic standard for sanitation. In least developed countries, landlocked developing countries and fragile settings, roughly two thirds of facilities had basic water services.

The report carries two cautions that matter more than the headline. Its estimates rest on the latest data available for each country, so they may not reflect a recent crisis in fragile settings. And the authors call on countries to move beyond measuring whether infrastructure is present, toward assessing reliability, safety and whether services meet the needs of patients and health workers. The people who produce the number are saying plainly what it cannot tell you.

What does a basic water service actually guarantee?

Presence, not reliability. A basic service means water from an improved source is available on the premises. It does not record whether the tap runs every day, whether the borehole holds through the dry season, or whether the volume is enough for a maternity unit. A facility with a well that fails for six weeks every summer can count as basic in a survey done in the wet season. That is not a flaw in the survey. It is the limit of a presence measure, and it is the gap climate stress lands in.

A basic water service tells you the tap exists. It does not tell you whether it ran in May.

Which services stop first when water fails?

The ones that need the most water per patient. WHO's essential environmental health standards for health care set minimum quantities for each kind of care, covering hand hygiene, cleaning, laundry, drinking and cooking: 5 litres per outpatient consultation, 40 to 60 litres per inpatient per day, and 100 litres per intervention in an operating theatre or maternity unit. Read in reverse, those numbers give the order in which care becomes unsafe as water runs short.

The pattern is uncomfortable. The services that fail first are the ones where water matters most to outcomes: births and procedures, where infection risk is highest. A facility can keep seeing outpatients through a water shortage and report normal activity while its maternity unit has quietly stopped being a safe place to give birth.

Why does this belong in a climate conversation?

Because water availability at a facility is seasonal, and seasons are shifting. Drought lowers groundwater and dries shallow wells. Heat raises demand for water exactly when supply is lowest. Floods can contaminate the source a facility depends on. None of these shows up in a presence measure taken once, and none shows up in programme data unless someone asks. What shows up is a dip in deliveries at a partner facility in the dry months, recorded as low demand. The same misreading turns up in cold chains during the monsoon, set out in the monsoon cold chain.

What should a programme know about its partner facilities?

Whether each facility's water runs all year, which services it stops or refers when water fails, and how long those gaps last. None of it needs new infrastructure to find out. Ask the facility in-charge directly, then check the answer against the programme's own records for the dry months.

• Source and seasonRecord each partner facility's water source and whether it has failed in the last two dry seasons. A basic rating in the national survey does not answer this.
• First service lostAsk which service stops or is referred out first when water runs short. The answer is usually deliveries, and it tells you where the programme's patients go instead.
• Read the dipCompare deliveries, procedures and admissions in dry months against wet months across two or three years. A consistent dry-season dip at one facility and not its neighbours is a water signal until shown otherwise.
• Plan the fallbackFor facilities that lose water, agree in advance where patients are referred, and whether water storage or trucking in the dry months is the cheaper fix.

Where is this heading?

Toward measuring reliability rather than presence, which is the direction the JMP itself is pointing. Programmes do not have to wait for the next global survey to get there. The facilities they fund already know when their water fails, and the programme's records already show what happened to patients when it did. Put the two together and a partner list becomes a map of where care stays available through the dry season and where it only appears to. The case for reading climate this way is in climate change is a healthcare story, and the term is defined in the glossary.

Questions worth asking after this

What share of health care facilities have water?

WHO and UNICEF estimate that 85 per cent of health care facilities worldwide had a basic water service in 2025. In least developed countries, landlocked developing countries and fragile settings, the share was roughly two thirds. A basic service means water from an improved source is available on the premises, not that it is reliable year round.

How much water does a health facility need?

WHO's essential environmental health standards set minimums of 5 litres per outpatient consultation, 40 to 60 litres per inpatient per day, 100 litres per operating theatre or maternity intervention, and 5 litres per staff member per day, covering hygiene, cleaning, laundry, drinking and cooking.

Which health services stop first when a facility loses water?

Reading WHO's minimum quantities, deliveries and surgical procedures need the most water per patient and become unsafe first, followed by inpatient care. Outpatient consultations need the least and usually continue longest, often with hand hygiene compromised.
